1990 Hyundai Excel ProblemsDriveability Issues Due to Faulty ECM Ground
A faulty engine control module (ECM) ground circuit may cause various issues including stalling, loss of air conditioning operation, and illumination of the Check Engine Light. Our technicians tell us that adding another ground wire to the ECM wire harness can often correct this issue.
The engine may stall when shifting the automatic transmission into reverse. This is commonly caused by a clogged transmission cooler line or fluid cooler. If this occurs transmission fluid flow will need to be restored by replacing the cooler and/or lines as necessary.
The manual transmission may become difficult to shift into third gear. This is common caused by worn synchronizers. Our technicians tell us that revised synchronizers are available to correct this concern.
